FORM IV UNDER SMPV(U) RULES 1981 Purpose : The licence in form IV is granted to transport compressed gases in pressure vessels on land by mechanically propelled vehicle. Such vehicle for transportation of compressed gases is called road tanker or in short, tanker. Note:-

1. For definition of pressure vessels or in short, vessels:- See item (t) of Rule 2 of SMPV(U) Rule 1981 2. For transportation purposes, the vehicle used may be fixed chassis or trailer chassis, depending on the quantity of compressed gas, to be transported. All chassis and the maximum allowed quantity of compressed gas for that particular vehicle are approved by Chief Controller of Explosives, Nagpur:a. Maximum quantity permissible for transport of compressed gas (flammable) 18 MT with GVW of 35.2 MT b. Maximum quantity permissible for transport of compressed gas (toxic) 15 MT with GVW of 35.2 MT All these requirements, load distribution etc. must also conform to the relevant section of Motor Vehicle Act as per Ministry of Surface Transport. 3. All the vessels which are mounted on chassis should be must be fabricated as per design code like IS-2825, ASME Sec. VIII Div. 1 BS:5500 and any other code as approved by the Chief Controller of Explosives, Nagpur (Rule 12 of SMPV(U) Rules 1981). The Chief Controller of Explosives, Nagpur has given approval to the various fabricators for fabrication of pressure vessel. So all vessels must be fabricated by fabricators approved by Chief Controller of Explosives, Nagpur as per terms and conditions laid down in the above said code or by the Chief Controller of Explosives i.e. by stage-wise inspections by third party, competent persons etc. Therefore prior approval for mountig of a pressure vessel of particular make and model of vessel is also to be approved in advance For transport, additional factor due to

acceleration/deceleration equal to 3g (pay load x 3/cross sectional area of the vessel). Additional factor should be taken while computing the design pressure. The vessel made of carbon steel meant for transportation of compressed gas should also be stress relieved

4. Fittings – Each vessel shall be provided with each of the following fittings all of which should be suitable for use with the gas at pressures not less than the design pressure of the vessel to which they are fitted and for temperatures appropriate to the characteristics of the gas and operating conditions, namely :i. ii. iii. iv. v.

Pressure relief valve connected to the vapour space; Drains; Contents gauge or maximum level indicator; Pressure gauge connected to the vapour space; Means of measuring the temperature of the contents of the vessel.

Note : For details refer Rule 18(2) under SMPV(U) Rules, 1981. Licensing Authority : Respective circle office of the Department of Explosives under whose jurisdiction the applicant belongs. The licence in respect of CO2 and Cryogenic vessel is granted by Chief Controller of Explosives, Nagpur. Procedure:

APPROVAL OF MOUNTING DESIGN OF PRESSURE VESSELS (MOBILE PRESSURE VESSELS)

Mounting of the pressure vessel on a vehicle is very important matter. The vessel should be so mounted on a particular vehicle chassis so that both in laden and unladen condition, the stability ratio is less than 1, the load on each axle does not exceed the permitted axle load as per vehicle manufacturers specification and regulations of Ministry of Surface Transport. Further, the vessel should maintain minimum 150 mm. Clearance from the cabin and 75 mm. from the rear bumper. In case of fixed chassis, the vehicle and guard reeling is also to be provided around the vessel. So that in case of its stopping, the vessel is not directly hit.

PROCEDURE FOR PERIODIC EXAMINATION & TESTING OF PRESSURE VESSELS : For ascertaining the safe status of the pressure vessels they are required to be periodically examined and tested. The pressure vessels meant for toxic/corrosive gases are to be tested at an interval of 2 years and those for other gases to be tested at an interval of 5 years. The periodic testing of smaller vessels for non-toxic/non-flammable gases or for flammable gases should comprise of ultrasonic thickness testing and hydrostatic tests at the designated test pressure as per the fabrication code. Vessels for toxic corrosive gases and large vessels for flammable gases are to be critically examined as follows :Non testing of ultrasonic thickness W.F & P.T, ultrasonic floor detection, dye penetrant test, hardness test and radiography test, in addition to hydro test should be carried out depending on the actual requirement based on defects noticed/anticipated. For hydro spheres additional tests for the supporting columns are also be carried out. Although Ammonia is the toxic gas, horton sphere for ammonia have been allowed by the Govt. to be tested at an interval of 5 years instead of 2 years. NOTE : 1) Testing of Horton spheres have been permitted by Chief Controller of Explosives to be carried out only by the specified inspecting agency who are also recognized as competent person. Other competent persons are not allowed to carry out periodic testing of hydro sphere. 2) Wherever the vessel cannot be safely filled with water, hydro tested for design parameters or where process of water cannot be treated, Chief Controller of Explosives may allow pneumatic test in lieu of hydro testing. In case of defects noticed during periodic inspection or retention of thickness below calculated minimum due to corrosion, the matter should be immediately brought to the notice of the Chief Controller of Explosives for his approval/action for carrying out necessary repairs or derating the vessel as the case may be.

Manufacture of safety fittings for pressure vessels

There are various safety fittings for pressure vessels as under: 1. Safety valve/safety relief valve 2. Excess flow valve 3. Spark Arrester Safety valve/safety relief valve

Excess flow valve

Spark Arrester

RECOGNITION OF COMPETENT PERSON/INSPECTOR : Pressure vessels are very critical equipments and hence manufacture of such pressure vessels are required to be carried out under stage inspection and testing by recognized inspector/inspecting agency. Similarly periodic inspection of pressure vessels and their fittings are also to be carried out by experienced and recognized competent persons. Any person desiring to obtain recognition as inspector or competent person should submit – 1) Application in form ‘A’ of Appendix 3 (for competent person), application in form ‘B’(for inspector) in form ‘C’(competent person). 2) Bio-data of the technical person of the organization giving details of experience in related field and copies of diploma/degree. 3) Scrutiny fee of Rs. 1000/- (for inspector) / Rs. 500/- (for competent person)

NOTE : Details regarding qualification, experience and minimum fees for inspectors and competent persons are given in Appendix 2. DEPARTMENTAL ACTION : If the technical persons of the applicant organization apparently seems to meet the requirements of the rule regarding qualification, experience etc., they are called for an interview to assess their depth of knowledge, requirements of code/standard/procedure etc. If the technical persons of the applicant organization are found to have adequate qualification, knowledge and experience (as assessed above), the organization is granted recognition. The recognition for inspectors in respect of stage inspection and testing of new pressure vessels during its manufacture, repairs etc., the recognition of the competent persons are granted under rule 18 (periodic testing of safety bulbs) rule 19 (for periodic testing of in-service pressure vessels), rule 33 (safety certificate for pressure vessels installation), rule 43 (safety certificate for mobile pressure vessels), rule 44(2) (for periodic thickness certification of mobile pressure vessels) depending on the sphere of experience of applicant organization. For periodic inspection of hydrogen sphere (spherical pressure vessels) only the organization who are recognized both as inspector and competent persons are authorized. Question ? 1.
